The validity of this measure has been supported through confirmatory factor analysis. It was also significantly correlated with established measures of anxiety and fear of hypoglycaemia in children. The internal consistency for the total score is 0.89 (Kamps et al, 2005).
A data set was constructed, and all data were entered twice and cross-checked for accuracy. The cleaned data were imported into SAS version 9.2 and statistical analysis was conducted using linear regression models and significance was assessed based on Type II sum of squares. Model fit was assessed using the F-statistic, and R-square values. Quantitative variables were modeled in several ways and the best fit chosen for the relationship being described.
